BOOT AND SHOE NAIL.

SPECIFICATION forming part of Letters Patent No. 334,361, dated January12, 1886.

Application filed April 25, 1885.

I?) all whom it may concern.-

Be it known that I, ANDREW EPPLER, Jr., of Boston, in the count-y ofSuffolk and State of Massachusetts, have invented certain new and usefulImprovements in Boot and Shoe Nails, of which the following is aspecification.

This invention relates to boot and shoe nails which are madeby cutting atubular blank into sections or headless nails, such nails being usuallymade and driven by an organized nailing-machine, which is provided withcutters for severing the wire into naillengths, and a driver for forcingthe nails as fast as they are formed into the boot or shoe sole, andturning or clinching their points or inner ends against a metal horn orlast within the boot or shoe. Heretofore, as far as I am aware, theouter ends of the nails of this class have been flat, and the drivennails have received no enlargements or heads at their outer ends by theaction of the driver.

My invention consists in making the nails with notches or slots in theirouter ends, and thus forming separable points, which are upset or turnedoutwardly by the driver, and when turned constitute enlargements orheads, which greatly increase the holdingpower of the nails, as I willnow proceed to describe.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents an enlarged side view showing two of my improvednails placed end to end. Fig. 2 represents an enlarged side view of oneof the nails, showing in dotted lines the form of the outer end or headof the nail after it is driven. Fig. 3 represents a section on line wat, Fig. 2.

The same letters of reference indicate the same parts in all thefigures.

In carrying out my invention I cut from a tubular blank of indefinitelength sections or nails a a, by means of cutters which make a V-shapedcut, and thus at one operation and without waste of metal form the notchor reentrant angle 5 in the outer end of the severed nail and the wedgeshaped point 4 of the succeeding nail. I thus form the nails entirelywithout waste of metal, instead of cutting away parts of the material toform the points, as heretofore.

When the nail is being driven, the driver of the machine strikes thenotched end of the Serial No. 163,427. (No model.)

nail and upsets or separates the spurs which form the sides of thenotch, as shown in dotted lines in Fig. 2, thus forming an enlargementor head of considerable size, and enabling the nail to hold the partsunited by it more securely than nailsheretofore formed and driven by thesame machine.

This improvement is particularly applicabie to nails made by inclosing acore of fibrous cord, 2, in a metallic tube or sheath, 3, as shown inLetters Patent granted to Oushman, No. 169,894, dated November 16, 1875,the tubular form of the metal part enabling it to turn or be upsetfreely, both at the notched head and at the wedge-shaped point, so thatthe angle of the cut made in forming said head and point is' notnecessarily made very acute, the comparatively-blunt point shown in thedrawings being clinched or upset by the independent turning of the twometallic prongs at the opposite sides of the tube constituting themetallic portions of the point, said prongs being separated by thefibrous core, and each being to some extent independent of the other. Asolid nail would require a sharper or more gradually-tapering point,which, if formed by the same cut that forms the notched head, wouldinvolve a notch of too great depth. I do not limit myself, however, to anail formed with a fibrous core, as a tubular nail without the-core maybe made with a notched head, which may be the converse of the point ofthe next nail or not. Loose nails with the notched heads may be suppliedto be driven by means independent of the machine that makes the nails.

I claim 1. A boot and shoe nail made of tubular metal, provided with aV- shaped notch at its upper end and a V-shaped point at its lower end,substantially as described.

2. A boot and shoe nail made of tubular metal with a fibrous core, andhaving a V- shaped notch at its upper end and a V-shaped point at itslower end, substantially as de scribed.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 22d day of April, 1885.
